Try Lesbosi, as in “Iraqi,” or “Israeli.” Or, more formally, Lesbosi Greeks. I.E., if you get rid of the N at the end of the word, there is less chance that somebody would have a Freudian slip and say lesbian by mistake.

After all, it’s been years since heterosexual folks at a party could say we are having a “gay old time”.
These poor Lesbosis are just going to have to get used to it.
